I've seen many receipes for how to install Node.js and Karma on Ubuntu 11.10, but none as simple as this.
Download latest Node.js from
http://nodejs.org/. Unzip the .tar.gz file into some directory (from here called nodeJsDir).
Open a terminal and type in the following commands:
cd nodeJsDir
./configure
make
sudo make install
There after simple install karma by executing the command
sudo npm install -g karma
Karma can now be started executing
karma start
Why Learn Node.js development: JavaScript is the language of the web now a days and indisputably for the near future, as there is no alternative to JavaScript on the horizon. Node.js itself is quite radical and it is the latest and near future of modern web application development joining hands with JavaScript as the sole server-side language.
